BR Pivot upgrade

[Just ken]

4 ¼" X 10 ¾" X 0.032" shim, soft aluminum preferred
2 7/8" X 10 ¾" X 010" shim, soft aluminum preferred
Disassemble, remove nylon sleeve and nylon puck bottom of base and top
Insert 4 ¼" shim into bottom, I put opening a tightening screw
Insert nylon sleeve, trimming as required, I put opening a tightening screw
Insert puck, trimming may be required, I left original and hammer into place. This keep shim in place. There is a hole in underside to pound out if necessary.

Assembly is a more work, as tighter
Disassembly, remove top first
Remove post from bottom before removing seat.
Vary thickness of shims to improve easy of assemble vs movement
Supplied top is a beautiful piece of wood but cannot sit behind rifle.
Working on new top that allows both side and behind rifle position if interested let me know

Isn't the piece your working on the bracket for the table top?
The swivel point for the BR table is on the base. As the table rotates, the table top and seat are fixed and rotate with the mast that connects the top and base. The rotation comes from the base and not the top.

I'm not sure what you're trying to do.

Did the same to both top and base. 2 7/8" goes in the top and 4 1/4" goes in the bottom, process is same for both. Shim in top is not as tight, but helps keeping it close before tightening it down. Shim in base is tighter to reduce slop when pivoting. The 0.032" thickness is a bit on the tight side, great for reducing almost all slop, just a little tight when its time to take apart.
